目的观察神经阻滞器在闭孔神经阻滞麻醉下经尿道膀胱肿瘤电切(TURBt)术中使用的可行性和效果。方法在30例膀胱侧壁肿瘤行TURBt术前,使用神经刺激器定位行闭孔神经阻滞麻醉。结果 27例闭孔神经反射消失;3例仍有轻微的内收肌痉挛。TURBt术中无一例发生闭孔神经反射。结论利用神经刺激器辅助定位行闭孔神经阻滞,可以提高闭孔神经阻滞的成功率和质量,有效避免在TURBt术中因闭孔神经反射导致的膀胱穿孔和神经血管损伤。
Objective To observe the feasibility and effect of nerve blocker used in transurethral resection of bladder tumor (TURBt) under the anesthesia of obturator nerve. Methods Thirty patients with tumor of the bladder wall underwent TURBt. The nerve stimulator was used to locate the obturator nerve block. Results The obstruction of the obturator nerve disappeared in 27 cases. There was still a slight adductor spasm in 3 cases. No case of TURBt closed obturator nerve reflex occurred. Conclusions The use of neurostimulator to locate the obturator nerve block can improve the success rate and quality of obturator nerve block and effectively avoid bladder perforation and neurovascular injury caused by obturator nerve reflex during TURBt.
